Abstract
An electromagnet consists of an external case 1 enclosing a first solenoid 2 inside which there are concentrically arranged an internal case 3 enclosing a second solenoid 4 wound around a pole core 5, said elements being closed at the top by a cover 6 and at the bottom by a ring 7 of nonmagnetic steel and by a pole shoe 8. A central aperture 9 extends across the full height of the electromagnet through cover 6, core 5 and pole shoe 8 and allows to deviate into pole shoe 8 the flux lines which tend to close at infinity. In this way the scrap pick is more compact and more evenly distributed, and the formation of cusps in the remaining scrap is reduced so as to shorten the time of operations such as the unloading of wagons, caissons, containers and the like.
